WDB ACR ACFT NOSE TIRES RAN OVER A METAL ENG COMPRESSOR BLADE DURING LNDG RESULTING IN BLOWING OUT BOTH TIRES ON LNDG ROLLOUT.

Narrative

ON LNDG AT LAGUARDIA; LOWERED NOSE OF WDB TO RWY. R NOSE TIRE BLEW FOLLOWED BY L NOSE TIRE AND DISINTEGRATION OF NOSE WHEELS. ACFT SWERVED ON NOSE STRUT AND WAS KEPT ON RWY BY AGGRESSIVE THRUST REVERSING AND BRAKING. ACFT WAS ON SPD; GS AND CTRLINE AT TOUCHDOWN. LNDG WAS NORMAL BUT NOSEWHEEL APPEARED TO FALL THROUGH FASTER THAN NORMAL. FURTHER INVESTIGATION FOUND SOME OTHER ACFT'S COMPRESSOR BLADE ON RWY WHICH MATCHED CUTS IN R NOSE TIRE. CRASH CREW WAS ON SCENE IN 10 SECONDS. CREW CHIEF ADVISED THAT THERE WAS NO FIRE -- THEREFORE; WE DID NOT EVAC. SUPPLEMENTAL INFO FROM ACN 208418: WE WERE FOLLOWING AN ACR ACFT THAT HAD CALLED EMER EQUIP OUT BECAUSE OF AN APPARENT HOT BRAKE CONDITION. I'M NOT SURE OF THE DETAILS BUT THE EMER EQUIP WAS AT THE SIDE OF THE RWY WAITING TO CROSS AS WE LANDED. THE ACFT CAME TO A STOP AT THE INTXN OF RWY 31-13 AND WE HEARD THE R MAIN TIRES BLOW. CAPT TOLD ME TO TALK TO PAX. I STARTED THE APU AND TOLD THE PAX TO REMAIN SEATED THAT WE HAD BLOWN A TIRE ON LNDG AND WOULD NOT BE ABLE TO MOVE THE ACFT AND THAT THEY WOULD SEE EMER EQUIP OUTSIDE THE ACFT. I OPENED THE COCKPIT DOOR SO THAT I COULD MONITOR THE CABIN. I CALLED COMPANY AND ASKED THEN TO SEND AIRSTAIRS AND BUSSES TO DEPLANE THE PAX WHILE THE CAPT AND FO COMMUNICATED WITH THE TWR AND EMER EQUIP. ALL ENGS WERE SHUT DOWN AS SOON AS THE APU WAS ON LINE BY THE FO. HE DID NOT WANT TO PANIC THE PAX WITH AN INTERRUPTION OF PWR IN THE CABIN. THE AIRSTAIRS ARRIVED AND WE DEPLANED THE PAX. NO ONE WAS HURT OR BRUISED AND MANY OF THE PAX COMMENTED THAT THEY DID NOT KNOW ANYTHING WAS WRONG UNTIL I MADE MY PA. THE FLT ATTENDANTS DID AN EXCELLENT JOB WAITING FOR THE COCKPIT COMMANDS AND DID NOT PANIC. THE CAPT WALKED THROUGH THE CABIN TO CALM THE PAX AND THEN DEPLANED TO INSPECT THE ACFT. AS I LEFT THE ACFT (ALL PAX WERE OFF) I WAS SURPRISED TO FIND THAT NOT ONLY WERE THE NOSE TIRES MISSING; BUT THE WHEELS WERE GONE AND THE ACFT WAS SITTING ON THE GND ON ITS AXLE SHAFT. THE CAPT HAD INSPECTED THE RWY AND TOLD US FROM THE SKID MARKS IT LOOKED LIKE THE R NOSE TIRE AND WHEEL EXPLODED AT TOUCHDOWN. DESPITE THE MISSING AND BLOWN TIRES THERE WAS LITTLE DAMAGE TO THE ACFT. THERE WAS SOME SHEET METAL DAMAGE NEAR THE WHEEL WELL AND THE #3 ENG COWLING. WE LEFT THE ACFT AND WENT TO OPS AND MEET WITH THE FAA REPRESENTATIVE AND WAITED FOR THE NTSB. WE MET WITH THE NTSB AND THE FAA THE NEXT DAY AT NEWARK AND THEN DEADHEADED BACK TO ATL AND MET WITH THE CHIEF PLT. THE CHIEF PLT INFORMED US THAT THEY HAD FOUND AN ENG TURBINE BLADE ON THE RWY AND IT LOOKED LIKE THAT MIGHT HAVE CAUSED THE FAILURE OF THE R TIRE AND WHEEL. APPARENTLY AN ACR LOST AN ENG ON TKOF 2 DAYS PRIOR ON RWY 4. IN SUMMARY; I BELIEVE THAT THE APCH AND LNDG WAS STABILIZED AND NORMAL AND DID NOT CONTRIBUTE TO THIS INCIDENT. I THINK THE CAPT DID AN OUTSTANDING JOB OF STOPPING THE ACFT AND ASSESSING THE SITUATION THAT RESULTED IN THE PAX DEPLANING THE ACFT WITH NO INJURIES AND MINIMAL DAMAGE TO THE ACFT.
